In this letter, we consider a cognitive wireless powered communication network (CWPCN), with a secondary wireless powered communication network (WPCN) that has cognitive ability to coexist with a primary communication network. To tackle the unfairness resource allocation issue in CWPCN, we extend proportional fair scheduler to this category of network. By utilizing the time division-based “harvest-then-transmit”...
In this paper, we extend proportional fair scheduling to a wireless powered communication network (WPCN) consisting of a base station (BS) and K rechargeable energy harvesting users (EHUs) that utilize dynamic time-division multiple access (D-TDMA). Each TDMA frame consists of an energy harvesting (EH) phase, which contains the RF energy broadcast by the BS, and an information transmission (IT) phase...
